Rio Solimões, Brazil.
Has been considered conspecific with O. motmot and O. superciliaris. Normally treated as conspecific with O. columbiana, O. araucuan and O. squamata. Differs from O. columbiana in much smaller size (2), broader and vaguer scaly pattern on browner breast (2), blacker vs slate-grey crown (2), rich brown vs olive tone to upperparts; from O. araucuan and O. squamata in much more chestnut-rufous undertail with less grey-black at feather bases (3), less rufous-toned rump (2), and blackish vs brown-shaded crown (2); from all three also in some vocal details. Proposed races caquetae (SE Colombia) and adspersa (E Peru) appear to be inseparable from nominate. Nominate and subaffinis apparently intergrade. Two subspecies recognized.
